cats and babies

Anyone have any advice/personal experience introducing the baby to the cats?

I'm currently in my 9th month. I'm getting a little worried as I see Gizmo so attached to me lately. He sleeps next to me in bed. Last night and this morning he attacked Krembo when she tried to come to me for petting. He is also a snuggler so I have to watch him closely. Krembo doesn't snuggle so she wouldn't try that with the baby. They are also both terrified of babies as far as we can tell, but we always had a toddler over with the babies so its hard to tell.
Gizmo is more scared than Krembo, but he's so possessive of me lately, I wonder how he'll take it.
